i am uploading files using attachment_fu ,i can upload files with
extension .txt, .xls, .doc but when i am going to upload .pdf extension
file i gives
Validation failed: Content type is not included in the list
My model file code is here .
class Model< ActiveRecord::Base
has_attachment :content_type =>['application/pdf','application
:storage => :file_system,
:size => 0.kilobytes..10000.kilobytes
Is there any issue for attachment_fu or anything else ?
